Count Frames in an Animated GIF
The animated GIF always makes me chuckle; on one hand they seem like a relic of the "old web", on the other hand they aren't going anywhere and their meme-like presence seem to only make them more popular. If you browse through my media blog posts archives, you'll notice that I've written a ton about animated GIFs, including how to tell if a gif is animated, how to get a screenshot of the first frame, converting GIF to WEBP, and more.
My curiosity recently brought me to asking how to detect how many frames were present in an animated GIF; as expected, ImageMagick had the answer:
identify -format "%n\n" bitcoin.gif | head -n 1
>> 101
What is this calculation useful for? I suppose if you have a media management site you could show each frame to a user so they could choose a poster
when converting to video. In any event, I was curious and simply had to find out!

We all know that MooTools 1.2 can do some pretty awesome animations. What if we want to quickly make two element swap positions without a lot of fuss? Now you can by implementing a MooTools swap() method.
